Pressure testing
1. The oven injector is used as a pressure
test point.
Remove the oven furniture. Remove
oven burner box retaining clips (one
spring clip from each side) and remove
box front cover. Replace one clip back
into the right hand side of the burner
box.
Remove oven burner by removing the
spring clip from the right hand side of
the oven burner and slide burner off
injector, whilst easing it forward and
taking care not to strain the F.S.D.
phial.
2. Connect the pressure gauge to the
oven injector. Check the supply
pressure by turning the thermostat on
and one hotplate tap full on and light
the appropriate burner.
The pressure should be either:-
(i) For Natural Gas 20mbar
(ii) For LP. Gas. The pressure must
be set to 28 mbar for use on
butane or 37 mbar for use on
propane.
3. Turn off the taps, disconnect the
pressure gauge and replace oven burner
and cover, ensuring that the F.S.D phial
is correctly located into the bracket on
the burner.
4. Check operation of the oven.
Checking the grill
Place the grill pan containing the grid, with
the handle attached, into the grill
compartment. Light the grill burner by
turning the grill tap full on and pressing the
ignition button on the fascia panel. As soon
as the burner is lit the button can be
released.
Checking the hotplate
Lift the lid. Fit the burner crowns and caps
ensuring that they are correctly seated. Fit
the pan supports.
Check each of the hotplate burners in turn
by turning the hotplate tap to its full on
position and pressing the ignition button. As
soon as the burners are lit the button can be
released.
Checking lid shut-off device
1. Lift the lid
2. Turn one hotplate tap to its full on
position and push the ignition button.
3. Close the lid. There should now be no
gas supply to the hotplate and the
burner will go out.
4. Turn off the hotplate and lift the lid. The
gas supply should now be restored to
the hotplate, when the tap is turned on.
Checking the second oven
1. Turn the second oven thermostat
control knob to Mk.1 and press the
ignition button. As soon as the burner
is alight the button can be released.
2. When the oven burner lights up there
should be a low gas rate at first to the
oven burner which is the F.S.D. bypass
rate.
3. When the F.S.D. phial has heated up it
opens the F.S.D. valve and the main
gas stream flows to the burner.
